the same sort of places (adjoining the southern beach) as the last 

 species. 



863. Atlantis mendax. 



Atlantis mendax, Wott., Ins. Mad. 376 (1854). 

 } Id., Cat. Mad. Col 115 (1857). 



Habitat Maderenses (P to S to ), in arenosis inferioribus submaritimis 

 inter plantas ibidem crescentes parce occurrens. 



Apparently peculiar, likewise, to Porto Santo of the Madeiran 

 Group, where it occurs about various plants on the drifted sand- 

 hills behind the sea-beach on the southern side of that island. 



864. Atlantis instabilis. 



Atlantis instabilis, Wott., Ins. Mad. 377 (1854). 

 , Id., Cat. Mad. Col. 115 (1857). 



Habitat Maderenses (P to S to , ftheo Chao ?, Bugio ?), sub lapidibus in 

 clivis saxosis paululum elevatis latens. 



Inhabits Porto Santo, like the preceding three species, but found 

 usually at a rather higher elevation beneath stones on the rocky 

 slopes and headlands, for the most part towards the northern coast. 

 I suspect that it occurs also in the Desertas ; for on the Ilheo Chao 

 and Bugio I met with some mutilated examples of an Atlantis which 

 I believe are referable to the instabilis. 



865. Atlantis excelsa. 



Atlantis excelsus, WoU., Ins. Mad. 378 (1854). 

 , Id., Cat. Mad. Col. 115 (1857). 



Habitat Maderenses (Mad.), -per atque etiam supra regiones sylvaticas. 



Widely spread over the sylvan districts of Madeira proper, and 

 ascending likewise even somewhat above them being occasionally 

 common under stones in comparatively open, grassy spots of a rather 

 lofty altitude. 



866. Atlantis Schaumii. 



Atlantis Schaumii et Fora, Wott., Ins. Mad. 379, 380 (1854). 

 , Id., Cat. Mad. Col. 115 (1857). 



Habitat (Mad., P to S to ), sub lapidibus hinc inde congregans. 



Found on the Ponta de Sao Lourengo of Madeira proper the low 

 rocky promontory in the east of that island as also on the summit 

 of the Pico do Castello in Porto Santo. It would seem, consequently, 

 to be attached to the eastern parts of the Madeiran Group.
